Q: It was a long day at work and I decided to stop at the gym before going home.  I ran on the treadmill and lifted some weights. I decided I would also swim a few laps in the pool.  Once I was done working out, I went in the locker room and stripped down and wrapped myself in a towel.  I went into the sauna and turned on the heat.  I let it get nice and steamy. I sat down and relaxed.  I let my mind think about nothing but peaceful, happy thoughts.  I stayed in there for only about ten minutes because it was so hot and steamy.  When I got out, I turned the sauna off to save energy and took a cool shower.  I got out of the shower and dried off.  After that, I put on my extra set of clean clothes I brought with me, and got in my car and drove home.
A:
How hot was the sauna?
